Taking Better Photographs



Topics include composition, light, colour, people, landscape and others. It's one thing to have a digital camera, it's quite another to take a decent pic. While we don't all have formal photography training this tips are a great starting point.




Free Video in a Spin


Was going through some old software links and was disappointed to learn that Avid no longer offers their Avid Free DV video editing software. Hunting around quickly I could find no alternative on their site either. A few minutes later, happily and by accident, I stumbled on this little free software gem from Pinnacle (a division of Avid) - Video Spin.

I did download it but it seemed to take a long time to install. Even so it looks really easy to use, why not take a test run yourself and leave comments on your experience.

Design Student Emergency Software

It's one thing to have a load of freeware to help you out in an emergency, but what if you don't even have your own computer to run it on? That's where Portable Apps can help.

The whole idea of a portable app is that you don't need to install it to run it. In fact you can run it straight from a USB memory stick or even a CD ROM on practically any machine (so long as it has the right spec). This means you can put the software on your USB stick and run it on any computer in your college, university or library, get your work done and all with minimal hassle.

So handy are these portable apps that I have come to prefer The GIMP portable to the fully installed version on my own PC.

Portable apps that caught my eye in particular are, The GIMP (open source Photoshop Equivalent), NVU (open source Dreamweaver/Frontpage equivalent) and Audacity (sound recording and processing), but there are others, take a gander yourself >

How does Google Work?

Slightly off topic I admit, but in case you happened to be wondering what really happens behind the scenes of your Google search...

Believe it or not, Google is not powered by an army of low-paid clerical mice using minature filing cabinets - take a look >

Is stealing wireless wrong?

Well let me think. Stealing is wrong! So stealing wireless is... erm... er... right? No. Wrong? At least this seems to be the opinion voiced in this BBC article - that is -no one appears very sure. Curious how when something appears to have little or no value on the surface, whether you are allowed to steal it suddenly becomes open for debate.

Basically, some bloke has been arrested for using his laptop in the street to connect to some other random person's unsecured wireless internet connection.

But, before your knee jerks, and you utter something completely foolish such as "Wot they arrest 'im for? Serves the other bloke right, they shud've secured their tinternet", you might want to:

  • Read the article
  • Scratch your head at the completely innacurate analogy of the article author
  • Guffaw at the more ridiculous analogies posted by the general public in response
  • Be mildly suprised at the bare faced cheek of the one who openly confessed to using his neighbours connection all the time:
Freeloading and proud of it. I just hope the person downstairs doesn't read
this. Bob, Bobsland

Before we go any further however, all good interactive media developers will already know how to be safe from Bob of Bobsland, by ensuring their wireless router is configured with WPA encryption enabled and MAC Address filtering. That way you keep your bandwidth all to yourself - and not share it with Bob and the Boblandians. And why not? After all you are paying for it.

However, some of our fellow internet users think that wanting to keep your wireless network to yourself is "odd". Consider this comment from "Richard, Nottingham":

Does it matter if Richard Branson, BT or any other major corporate company doesn't get a few more pounds? If someone wants to share then fine, if you're a bit odd and aren't interested, then put a password on it. Don't give me the 'I'm paying, so why should someone else get something out of it' argument either.
Richard, Nottingham

Of course Richard of Nottingham made no comment about whether it was"odd" to want to keep his cash to himself while he freeloads your broadband connection.

Some no doubt really think that wireless signals will go to waste if not used (indeed the author of the BBC article seems to think so - hence their crass analogy to open their article). But this is not the case. In some situations piggy-backing someone else's connection will do little more than slow their data transfer rate. In other cases you may be robbing them blind - this occurs if the user has a broadband contract that has a cap or limit on the ammount of data they can transfer in a month. If the freeloader downloads 10Mb, he has robbed their paying host 10Mb worth of data transfer.

Judging by some of the comments, this would not only not be stealing, but the wireless owner would be asking for it. As if someone savvy enough to find the unsecured wireless somehow lacks the power of choice in the matter. The same people equate it to leaving your car doors open and say you should have no cause to complain when it gets nicked. Clearly, leaving a car door open is a crime worthy of having your car permanently confiscated by a thief, while being a car thief is a profession worthy of a free car. These people are blatantly missing the point while they come up with worse and worse analogies for at best freeloading and at worst stealing from their neighbours.

The problem with blaming the victim for their carelessness, and placing the blame on them, is potentially much worse than ignoring the obvious fact that the thief had a choice. There are rights issues at stake here. In fact there is real danger in setting a precedent that it becomes the owners job to make access impossible or "right of access" is assumed to be granted. Legal precedent tends to spill over into other situations. This is not a direction we want to go.

When analogy ping-pong fails, and the crooks still think they have a right to piggy-back, I have this to say:

To all the cheapskate freeloading parasites out there - especially those who regularly leech off their unwitting neighbours. If you don't want to pay BT for your own connection, you should knock on the persons door whose connection you are using, and offer to go halves. Now that's sharing and paying your own way. You also might then feel differently if leech number 3 came along and wasn't sharing the bill. If you're freeloading, taking not giving, you're being a parasite! Get your own connection or at least offer to pay some to your host and be a drain on others no longer.

I wonder if the BBC will publish my comment.

Dealing with "Click to Activate" for browser based Flash content

One thing you may have noticed when browsing websites containing Flash content, is that you now need to "click to activate", before you can interact with it. This is not IE being more secure, but rather it is a result of legal action from a company called Eolas who apparently owns a patent that has something to do with how plugins and browsers work together. Without going into the legal rambling the real issue for interactive media creators is how you get around it.

So you have crafted some smooth graphics and smoother actionscript all designed to respond to the mouse at it's merest touch. You object and embed it into a web page, the user opens the page, the mouse moves over the flash movie and... nothing happens.

At least not what you intended. Instead a grey box appears around the flash content and a message appears telling the user to "click to activate". That's alright for you - you know there is a flash movie there to activate. But do your users even know what the message means? Besides that, who wants to introduce another 'click' before your page works properly.

If you don't know what I mean, take a look here (click) and mouseover the yellow box on the home page.

The solution

Well, in fact there are several suggestions. But rather than go into details here repeating what others have said, take a look for yourself:

While Microsoft is not without its anti-fans wishing it ill luck, it is ironic that when in this case they are not having things their own way, the result is also very annoying for end users too.

Job Hunting Online? Graduates and others be aware...

Now is the time for all good graphics and interactive media graduates to start hunting that elusive, and highly competed job. But while you trawl the job pages, or more likely join all the job-hunting websites you can find, take a gander at this BBC article, and note the tips for personal security.

The BBC reports that Monster.com, the US based jobs site was hacked and the personal information of over 1 million users stolen. Not much you as a user can do about that type of security breach, but you can go for damage limitation. In particular the BBC reported the following tips from computer security firm Symantec:
Symantec said users should always limit contact information posted to job websites and to use a disposable e-mail address.

"Never disclose sensitive details such as your social security number, passport or driver's license numbers, bank account information to prospective employers until you have established they are legitimate," said the firm.
